Comparison of major and minor intron conservation between human and Arabidopsis thaliana

Major			Minor
N cons	N var	Conservation (%)	N cons	N var	Conservation (%)	p Fisher
2052	14 162	12.7	7	120	5.5	0.015

N_cons indicates the number of introns of each type conserved as the same type in both human and Arabidopsis. N_var indicates the total number of introns (of both species) present in the alignments where the corresponding position in the opposing sequence either does not contain an intron, or contains an intron of the other type.
